Verify example snippets with the picky warning options used when
compiling curl core code and standalone example code. Also test with
clang. Extract picky warnings available via a new, internal, CMake
option.
Also:
- fix issues found.
- tried reproducing #22638 in CI (specifically the casts for `%p`),
turns out it needs apple clang 17, and no longer reproducing with
apple clang 21.
Follow-up to 5c61e16869 #22638
Closes #22639

# NAME
|
|
|
|
CURLOPT_PREQUOTE - commands to run before an FTP transfer
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PREQUOTE,
|
|
struct curl_slist *cmds);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a pointer to a linked list of FTP commands to pass to the server after
|
|
the transfer type is set. The linked list should be a fully valid list of
|
|
struct curl_slist structs properly filled in as described for
|
|
CURLOPT_QUOTE(3).
|
|
|
|
Using this option multiple times makes the last set string override the
|
|
previous ones. Set it to NULL to disable its use again.
|
|
|
|
libcurl does not copy the list, it needs to be kept around until after the
|
|
transfer has completed.
|
|
|
|
While CURLOPT_QUOTE(3) and CURLOPT_POSTQUOTE(3) work for SFTP,
|
|
this option does not.

# DEFAULT
|
|
|
|
NULL

|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl;
|
|
struct curl_slist *cmdlist = NULL;
|
|
cmdlist = curl_slist_append(cmdlist, "SYST");
|
|
|
|
curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode result;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/foo.bin");
|
|
|
|
/* pass in the FTP commands to run */
|
|
curl_easy_setopt(curl, CURLOPT_PREQUOTE, cmdlist);
|
|
|
|
result = curl_easy_perform(curl);
|
|
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
curl_slist_free_all(cmdlist);
|
|
}

# RETURN VALUE
